川中丘陵区防护林改良土壤作用研究
Study on Soil Amelioration of the Protection Forests in the Hilly Area of Central Sichuan
摘要
Abstract
The article studied the influence of different protection forest types on the physicochemical properties of soil in the hilly area of Central Sichuan. TheResultshowed that the soil clay particle, physical clay particle content, bulk density, porosity, capillary moisture content, field capacity, field effective capacity, effective soil water storage per hectare, soil nutrient storage and soil available nutrient supply were all higher than that of contrast plot, standard plot, forest land and unforested land, which indicated protection forest has evident amelioration on soil; the amelioration degree depends on the composition and structure of the forest vegetation besides of species collocation. The study has important guiding significance on the ecosystem restoring and reconstruction of severe soil erosion area.关键词
